I have a 6yo DD who is a tomboy and has only close male friends. I also have a 4yo DS with potential SEN. When my DD has a play date my DS wants to join in especially as he's very impressed with older boys. Not unusual but I'm finding my DD and her friend gang up and essentially bully my DS and I find their behaviour is unacceptable. My DS gets very excited and can led to aggression so it usual ends in me getting involved and pulling him away. I've tried to organise play dates when my DS is out at a club or with another relative but sometimes he is around. I engage with him and say we are having a play date, but unsurprisingly Mummy isn't as much fun as other children! I'm really upset by my DDs behaviour and how she treats her brother. I'm an only child so I'm aware that this could be usual sibling behaviour but i hate it. Any advice would be appreciated. Thanks
